The top medical imaging and radiology news for histiocytoma healing process may 6, 2019

Dr. Luke oakden-rayner released another excellent AI blog that has people in histiocytoma healing process the radiology and artificial intelligence arenas talking. Oakden-rayner targeted some largely agreed-upon beliefs and approaches, and although he warns readers to take his opinions “with salt for best results,” we’ve found his perspectives usually come well-seasoned. Here they are:

• no medical advance is going to be achieved by a histiocytoma healing process team who has designed a fancy new model for the histiocytoma healing process task. If a team builds its own model for medical research histiocytoma healing process instead of using an already-available AI model, they’re actually doing machine learning research because “the very process of building and tuning your own model histiocytoma healing process means you will almost certainly overfit to your particular data.”

Following recent incidents where imaging staff used incorrect rubidium-82 generator solutions, leading to excess radiation exposure during PET scans, the FDA issued a warning and instituted new safety labeling histiocytoma healing process requirements. The FDA now requires a boxed warning on rubidium 82 histiocytoma healing process generators that reminds operators to use the correct solution to histiocytoma healing process elute the generator (to extract rubidium 82) and to carefully follow safety procedures.

The reported incidents used calcium-containing solutions such as lactated ringers to elute the system, instead of the required 0.9% sodium chloride injection USP. In these cases, the calcium can interact with the generator’s radioactive strontium 82 and strontium 85 isotopes, which are then inadvertently injected into the patients along with histiocytoma healing process the rubidium, potentially leading to a range of medical issues (suppressed bone marrow and immune system functions, radiation-induced cancers).

• canon – canon struggled in Q1 as its revenue fell by 10% to ¥864.5 billion ($7.7b) and its net income sunk by 45.2% to ¥31.3 billion ($281m – still pretty good). Like nearly every other canon business unit, canon medical systems struggled in Q1 (revenue -6.5% to ¥109.4b/$984m; OP -36% to ¥6.7b/$60m), ending a streak of three straight positive quarters for the histiocytoma healing process medical division.

• hitachi – hitachi didn’t release its Q4 financials, but its full 2018 fiscal year that ended in march histiocytoma healing process brought a 1% revenue increase to ¥9.48 trillion ($85.3b) and 34.6% drop in net income to ¥321 billion ($2.89b – yes, hitachi is that big). Hitachi’s healthcare business had ¥176 billion ($1.58b) in revenue and ¥4.3 billion ($38.7m) in operating income during the full fiscal year (healthcare comparison vs. 2017 unavailable).

• samsung – samsung struggled in Q1 as revenue fell by 13.5% to KRW 52.39 trillion ($45b) and operating profit plummeted 60% to KRW 6.23 trillion ($5.35b) due to challenges in its memory and display businesses. Samsung’s consumer electronics division (which somehow includes healthcare) saw revenue increase 3% to KRW 10 trillion ($8.58b) and operating profit rise slightly to KRW 54 billion ($46m).

• siemens healthineers – A strong imaging performance (+7% to €2.137/$2.395b) drove siemens healthineers’ 5.8% Q2 revenue growth to €3.505b ($3.909) and a 24% net income increase to €381m ($427m). Siemens’ imaging business appears to have outperformed its big four rivals histiocytoma healing process (and the overall market), due in part to strong performance in europe.

The study looked at 74 patients with mammographically detected suspicious histiocytoma healing process microcalcifications who underwent breast US and had the microcalcifications assessed histiocytoma healing process with SWE. The SWE assessments revealed that the group’s 13 malignant calcifications had “significantly higher” stiffness than the 16 benign calcifications. SWE diagnosed malignancy with a 0.89 AUC, 100% specificity, 69% sensitivity, 80% negative predictive value, 100% positive predictive value, and 86% accuracy.

The pigg-O-stat pediatric immobilizer, a nearly 60-year-old contraption used to keep children still during X-ray exams, went viral last week when many in the non-medical community caught their first glimpse of how kids look histiocytoma healing process when they’re strapped into the pigg-O-stat (cute, but definitely not comfortable). Reactions to the pigg-O-stat swept across social media and online publications, perhaps making last week the awareness high point for pediatric histiocytoma healing process radiology and radiation safety in recent memory (this is the reason we’re covering it). That said, it’s worth noting that the pigg-O-stat also went viral for the same reasons in 2015.

• the hong kong polytechnic university (polyu) developed a handheld 3D ultrasound imaging system that’s intended for mass scoliosis screening and is positioned as histiocytoma healing process a possible X-ray alternative. The new 5kg “scolioscan air” is a scaled-down version of polyu’s 150kg scolioscan system that launched in 2016, combining a wireless ultrasound probe with an optical marker, a depth camera, and a laptop or tablet PC with dedicated 3D spinal histiocytoma healing process deformity analysis software to detect and measure signs of scoliosis.

• A single-center study from a NYU led team reveals that up histiocytoma healing process to 37% of CT pulmonary angiography (CTPA) scans for potential pulmonary embolism (PE) were performed without the support of imaging order guidelines. The early 2016 study looked at 212 consecutive CTPA scans histiocytoma healing process and found that between 53 (25%) and 79 (37%) studies were guideline-discordant (depending on the scoring system), with 46 (22%) studies discordant under all three scoring systems used in the histiocytoma healing process study. However, this may not be as reckless as it may seem, as 18 (39%) of the discordant scans “had at least one patient-specific factor associated with increased risk for PE but not histiocytoma healing process included in the risk stratification scores (eg, travel, thrombophilia).”

• the university of toronto signed a two-year deal with international medical solutions (IMS) to use the company’s IMS web viewer to test/train its radiology residents in a simulated emergency radiology environment. The university of toronto project is part of a larger histiocytoma healing process RSNA-funded study on the effectiveness of ER simulation testing that histiocytoma healing process will include up to 20 north american universities.

• research from a medical university of south carolina-led team found that an automated algorithm can accurately predict histiocytoma healing process major adverse cardiovascular events (MACE) by analyzing plaque characteristics in CCTA scans with more accuracy histiocytoma healing process than using traditional clinical risk factors. The study looked at 45 patients with suspected coronary artery histiocytoma healing process disease (16 experienced MACE in the the last year) who underwent CCTA, achieving 77% accuracy and a 0.94 AUC with the algorithm-alone and 87% accuracy and an AUC of 0.94 by combining the algorithm with clinical risk factors (vs. 63% and 0.587 AUC with just clinical factors). The researchers suggested that the algorithm’s ability to reduce variability and improve efficiency could help histiocytoma healing process CCTA achieve a more mainstream clinical role.

• british columbia’s health minister revealed impressive results from its efforts to histiocytoma healing process improve MRI accessibility, increasing the total number of MRI scans performed in the histiocytoma healing process province in the last year by 23% (43,993 additional scans) and increasing scan volume in some areas by almost 87%. These increases were made possible by shifting 10 of the histiocytoma healing process province’s 33 MRI machines to a 24×7 schedule, buying two privately owned MRI clinics in the fraser valley histiocytoma healing process (east of vancouver), and increasing its MRI budget by $11 million. The BC government will add another $5.25 million to its MRI budget next year, funding 15,000 additional MRI scans.

• A UCSF-led research team released the latest study validating the effectiveness histiocytoma healing process of 68ga-PSMA-11 in diagnosing prostate cancer (here’s other recent studies from UCLA and germany). The new research (n = 150) from the SF bay area team found that 68ga-PSMA-11 is extremely accurate at detecting cancer metastases in patients histiocytoma healing process with biochemically recurrent prostate cancer (up to 100% sensitivity per region, 89.8% per patient) with “high positive predictive value” (up to 100% per region, 91.5% per patient) and “almost perfect interrater reliability” (κ = 0.78–0.87).

• A new federal spending bill could delay the USPSTF breast histiocytoma healing process cancer screening guidelines another year to january 2022, which may not be surprising given that the controversial screening histiocytoma healing process recommendations have been consistently delayed since they were first published histiocytoma healing process in 2009. The delay will help ensure full coverage (no deductibles or copays) of annual screening mammograms for women 40 and older by histiocytoma healing process recognizing the previous 2002 USPSTF recommendation.

• research from a UCSF and mayo clinic team found that histiocytoma healing process breast ultrasound’s high NPV makes it the best initial imaging option histiocytoma healing process for palpable lumps after mastectomy. The study looked at 101 patients (118 cases, 75 with ultrasound and 43 with US+DM), identifying nine cancers with only ultrasound and three cancers using histiocytoma healing process US+DM. Of the 104 palpable nonmalignant lumps, ultrasound had a 97% negative predictive value and a 27% positive predictive value 2 (PPV2).

• chinese researchers developed a deep learning model that might be histiocytoma healing process able to confirm, locate, and measure chronic myocardial infarction using cardiac cine MRI without histiocytoma healing process the use of gadolinium. The study used cardiac cine MRI scans from 212 patients histiocytoma healing process (80% for training, 20% for testing), with the DL model achieving respective per-segment sensitivity and specificity of 89.8% and 99.1%, and a 0.94 AUC.
